Maven中心仓库修改为阿里云，加速网络访问

Maven 仓库默认在国外， 国内使用难免很慢，我们可以更换为阿里云的仓库。

maven.aliyun.com代理了很多公共的maven仓库。使用maven.aliyun.com中的仓库地址作为下载源，速度更快更稳定。

配置指南

maven配置指南

打开maven的配置文件(windows机器一般在maven安装目录的conf/settings.xml)，在标签中添加mirror子节点:

    aliyunmaven
    *
    阿里云公共仓库
    https://maven.aliyun.com/repository/public

如果想使用其它代理仓库,可在节点中加入对应的仓库使用地址。以使用spring代理仓为例：

    spring
    https://maven.aliyun.com/repository/spring
    
        true
    
    
        true
    

gradle配置指南

在build.gradle文件中加入以下代码:

allprojects {
    repositories {
        maven { url 'https://maven.aliyun.com/repository/public/' }
        mavenLocal()
        mavenCentral()
    }
}

如果想使用maven.aliyun.com提供的其它代理仓，以使用spring仓为例，代码如下:

allProjects {
    repositories {
        maven { url 'https://maven.aliyun.com/repository/public/' }
        maven { url 'https://maven.aliyun.com/repository/spring/'}
        mavenLocal()
        mavenCentral()
    }
}
